Atmosphere and Oceans Weather, Fronts, and Forecasts: From observations to predictive models by Anne E. Egger, Ph.D. Reading Quiz Teach with this 1. Standardization of instruments like thermometers, barometers, and hygrometers was an important step of establishing a network of weather stations because: Each instrument measured something different People were not very good at recording their observations The instruments could be carried in balloons Measurements taken at different locations could be compared 2. The British government established the Meteorological Office to __________. Collect and analyze weather data to improve forecasts for mariners Advance the science of meteorology Develop a theoretical basis for forecasting Provide a job for Robert FitzRoy 3. Both James Glaisher and Robert FitzRoy made important contributions to the science of meteorology by __________. Expanding networks of weather stations Making maps that showed weather data in specific locations Standardizing processes for collecting and reporting weather data All of the above 4. Jacob Bjerknes identified and tracked "convergence zones" using ground-based data, but eventually stopped using this language and instead described steering lines and squally lines connected in a cyclone. What led to this change? They had access to data collected higher in the atmosphere and over a broader area. The suggestion came from a visiting American student. They had difficulty tracking convergence zones over the ocean. They needed to produce agricultural forecasts three times a day. 5. The Norwegian Cyclone Model is a predictive model that does a good job of explaining __________. weather all over the world weather in the temperate zones hurricane formation cyclones in Norway 6. Fronts are boundaries or transitions between __________. climatic zones layers of the atmosphere cyclones air masses 7. An air mass that formed over the Pacific Ocean just north of the equator would be labelled __________. mP (maritime polar) mT (maritime tropical) cT (continental tropical) cP (continental polar) 8. The weather forecast you look at shows that the temperature over the next two days will drop from 80° to 60° and there are thunderstorms predicted. Which kind of front is most likely passing through? A warm front A cold front An occluded front A stationary front 9. When you go outside, you see cloudless skies, the air is warm and dry, and there is almost no wind. Which kind of pressure system are you most likely in? A stationary front A low-pressure system A high-pressure system A transition between systems 10. The weather map shows a cold front in the eastern United States (the blue line with blue triangles) with a band of heavy rain (the dark green shading). Which direction would you expect the cold front to move over the next few days? To the west To the east To the north It will remain stationary Score Quiz
